COMBINED DISK l-IARROW AND SEEDER.

SPECIFICATION forming part of Letters Patent No. 394,128, dated Decanmr4, 1888.

Application filed May 28, 1887. Serial No. 239,661, (No model.)

T0 all whom if may concern:

-e it known that l, FRED. ll. NORTON, a citizen ot the l'nited States,residing at. Gouverneur, in the county ot' St. Lawrence and State ot'New York, have invented certain new and uset'ul lmprovt-mients in(ioinbined Disk Harrows and Seed ers, of which the following is aspecification, reterence being had therein to the accon'lpaityingdrawings.

lli`igure l is a top or plan view, partly broken away, with the gangsout ol' line. Fig. 2 is a bottom view, with the gangs in line. Fig. 3 isa rear elevation ot' Fig. 2. Fig. -tis an end view looking in thedirection ot' the arrow, Fig. l. Fig. 5 is a vertical section on line .rrr, Fig. Si, looking in the (flirection ot the arrows 2, same figure,showing in t'ull lines some ot the gangdraft connections (which wouldnot naturallyv be seen in this figure) to illustrate their operation.Figs. l, 7, S, il, lt), ll, 12, lil are details enlarged, part oi' themillustrating moditications.

A is the pole, and A the seat and standard.

In one class ot' disk harrows the inner ends of the gangs are soconnected to each other that they necessarily rise and fall together byreason ot' their being attached to each other in such manner that theyare incapable of vibrating vertically independently ot' each other. lnanother class the inner ends of the gangs abut against each other oragainst an interposed device ot' some sort which permits the inner endotl either gang to vibrate vertically independently practically ot' theinner end ot' the adjacent gang. Two advantages are incident to thissecond class, to wit: a more ready conformation or adajiitation ot' theposition of one gang to the contour oi' the surface ot' the ground beingoperated upon, and the relieving ot' the bearings by which the gangs areconnected to the (lratt-t'raine from the inward thrust produced by thedisks when in operation. An illustration oit" this second class or typeis found in Patent No. 351,025 to A. Corbin, .l r., in which it isproposed that the inner ends ot' the gangs be provided with rounded endsto abut against each other or against an interposed stationair-y plate.My harrow belongs to this second class, and one part of my inventionrelates to the combination, with the i inner ends ot' the gangs, ot apin which is adapted to receive upon its ends the inward thrust ot thegangs, and thus relieve the box ing otl the axles t'rom the friction andwear to which they would be otherwise subjected, and at the sametimepermit the inner ends oli the gangs to vibrate in vertical planes, theends ot' the pins serving as pivot-points about which the gangs canvibrate in every direction as maybe required in the ordinary working ofthe harrow. Each end ot' this pin is free to vibrate vertically aboutits opposite end,whieh is seated in, but disconnected t'rom, theadjacent gang-axle.

Other parts ot the invention relate to teatures ot' construction andcombination which will be fully explained and referred to in the claims.

,l 13; o, Figs. l, to, 11. and '12, is the gangaxile beam, bolted firmlyto the tongue and forming therewith the mainframe. The axlebeam is madeot' one piece ot' angle-i ron bent downward at its ends and connectedwith the gangs, as will be fully explained.

(l (y are the gang-axles, preferably round, in cross-section, andconnected near their outer ends to the downward-projectin g ends ot' thegang-axle beam.

(7" C is a two -part tubular boxlng surrounding one ot' thespacing-thilnbles. It has a circumferential rib, c, with upward anddownward lugs arranged in pairs.

ZF b2 are bars bolted at their upper ends to the inward, projecting webb, and are bent into shape to surround loosely the rib of the tubularboxing. b b are bolts 4supported in the bars b l) above and below thetubular boxing, and at such distances apart as will permit anup-and-down movement otl the main frame relatively to the gang-axles.The lugs straddle these bolts and are of such length as to permit thisup-and-down .movement with out escaping` from the bolts. As amodification l propose to extend downward the ends B`2 of the beam farenough to receive a yoke, b2, which has its ends bolted to the web l) insuch position as to receive and support the tubular boxing,substantially as shown in Fig. l2; or l may connect the gangs with thegangaxle B by means of stirrups Z13, surrounding IOO the tubular boxing,the ends of the stirrnp passing through the inward-projecting web andbolted thereto, as in Fig. 13.

In other figures I have shown metal downhangers B B', arranged in pairsat each end of the ordinary cross bar or plank, B3, and upon oppositesides thereof. In connection with these down-han gers I propose to usebolts b b upon opposite sides of lthe tubular boxing and at about thesame distances apart vertically as are the corresponding bolts and thelegs of the stirrups in the other figures; but, as above stated, Iprefer the T-iron continuous metal'gang-axle beam, which is adapted foruse generally in this class of harrows for connecting the gangs with thetongue or draftframe. y

I do not claim to be the first to use a bent iron bar in theconstruction of a disk harrowframe; but, so far as I am aware, the useof T-iron for this purpose is new, and it possesses many advantages overa flat bar, whether the same be used with its tlat face -uppermost orwith its edge uppermost. For instance, with a T-iron beam having itsends bent downward with the fiat surface uppermost and its central ribprojecting downward from the horizontal part and inward from thevertical end portions I provide a desirable broad flat bearing for thefeet of the brackets of a seed-box, to be hereinafter described, and canutilize advantageously the central web b as a support for either thebars b2 or the stirrup shown in Fig. l2, each of which can be bolted tothat web with one of its edges abutting against the inner face of theflat upper and outer web, whereby the bolts are largely relieved fromstrain and a much greater strength and durability attained than would bepossible with any of the constructions heretofore known.

At the inner end each gang-axle carries a daring shell, D d, preferablylof chilled iron, or other suitable hard metal, and in ordinarymanufacture I propose to cast these shells directly upon theirrespective axles.

E e e is a sleeve-bearing surrounding the axle between the smaller 'endof the shell and the adjacent disk.

The disks F F are of any usual sort placed upon the axles withinterposed spacing-thimbles, and clamped together by a nut on the outerend of the axle. The inner disk, F, has a central opening of such sizeas to fit over the larger end of the shell, to which it may be fastenedby rivets passing through the disk and the flange d at the inner end ofthe shell.

G is a thrust-pin arranged within the shells and engaging at its endswith the inner ends of the axles, or, when preferred, the shells may beso formed as to cover or inclose the inner ends of the axles, as isindicated at the right-hand end of the thrust-pin in Fig. 3, to providea hardened surface. I prefer to make the thrust-pin of chilled iron orhardened steel, with both its ends cone-shaped and of less diameter thanthe inner diameters of they shells to permit the vibrations of thegangs. It will be seen that although this pivotal thrust-pin receivesthe inward thrust of the gangs, yet by reason of the inner diameter ofthe inner ends of the shells being much greater than the diameter of theadjacent portions of the pin the inner ends ot' the gangs can rise andfall relatively to their outer ends and their bearings in the frame, soas to conform to the surface of the ground over which they are drawn.

H I 1' t' is a bearing-block, preferably of cast-iron. The horizontalpart II may have upward-projecting lips to embrace the sides of thetongue an d support it against splitting. The vertical part I is slottedto receive a pivot-bolt to be described.

.I is an equalizer mounted centrally upon a pivot-bolt, j, which passesthrough the slot and carries at its rear end a thimble and nut, thelength of the thiinble being a little greater than the thickness of theequalizer, so that the pivotbolt can be screwed up tightly against theslotted upright I and permit the equalizer to vibrate freely about it topermit not only the vibration of the inner ends of the gangsindependently of one another in vertical planes to conform to thesurface of the ground, but also to permit the gangs to occupy differenthorizontal and parallel planes, whereby the harrow is adapted topulverize the ground to uniform depth under a great variety ofcircumstances.

In the Corbin harrow above referred. to, when the gangs are assumingsuch various positions at work, the inner en ds of the gangs must eitherrub against each otheror against the interposed plate, whereas in myharrow the gangs vibrate about the ends of the interposed pin, whichserve as pivot-points for that purpose, either end of the pin being freeto rise and fall about its opposite end as a center. In order to providefor such movements without having the pin assume an undesirable angle toeither of thedisk-gangs, and to prevent placing the inner disks too Yfarapart, I employ a long pin and then combine with the inner ends of theaxles shells which overlap the pin and carry disks at their inner ends.Again, another function of these shells is this: They guard against lossor accidental displacement of the pin in case,A from any cause, theinner ends of the gang-axles should be separated from each other fartherthan they usually are when in operation, it being impracticable, or atleast undesirable, to attacheither end of the pin to its adjacent gang,and it will be readily understood that by reason of the pin beingperfectly loose within the shells its presence facilitates t-hevibration of the inner ends of the gangs independently of each other inall directions, either end of the thrust-pin being free to vibratevertically about its opposite end whenever the movement of the inner endof either gang necessitates such movement.

IOO

IIO

The conical form of the shells greatly fa` cilitates the escape of dirt,should any fall from the disks upon the pin and enter the mouths of theshells. Therefore there is little or no liability of dirt getting to theinner ends of the shells and grinding oit' the outer ends of the pins.In order to insure sufficient strength and rigidity of the pin, Iincrease its diameter at the center, or by loosening the nut it,together with the equalizer, may rise and fall together within thelimits of the slot.

j' j are links pivoted at their uppcrendsto the equalizer and at theirlower ends to the lugs e e of the tubular bearing, whereby the weight ofthe main frame and the driver may be made to resist any upward movementof the inner ends of the gangs, it being apparent that if the pivot-boltbe locked in a lower position in the slot than that shown in Fig. 3 theinner ends of the gangs will be depressed relatively to their outerends, and consequently the center disks of the harrow will tend to cutdeeper into the soil than will the outer ones.

I am aware that it is common to connect a horizontal bar to the innerends of the gangs, so as to maintain them in a substantially commonhorizontal plane to insure that they shall at their inner ends ent tothe required depth, and hence I do not claim such bar; but I believemyself to be the,lirst to use a pivoted bar the ends of which canvibrate up and down in combination with the inner ends of the gangs, forthe purpose ot' regulating their depth of eut.

To assist in moving forward and regulating the depth of eut of thedisks, I employ a vibrating thrust-bar connected at its rear end to themain frame, with devices to support and adjust its front end. To permitthe inner ends of the gangs to vibrate vertically or independently, Iconnect them wit-h the thrust-bar by draw-bars, and to facilitate theadjustment of the thrust-barI employ a link within reach of the driver.

Referring particularly to Figs. :2, l, and 5, K K represent the.liaw-'lJai-s, connected at their rear ends to the bearings E E of thegang-axles by pivots, which pass through the draw-bars and the lugs e e.These draw-bars are pivoted at their front ends to the frontdownward-projecting end of the thrust-bar K, which latter has its rearend connected to the main frame.

By an examination of Figs. i and 5 it will be readily understood thatwhen these parts are in the position shown in Fig. i the inner ends ofthe gangs are in rear of their outer ends 5 but when the correspondingpartsthat is, the thrust-bar and draw-bars-are in the position shown inFig. 5 the gangs are in substantially a straight line and at rightangles to the line of draft. It will also be seen that when the gangsare being shifted from one of these positions to the-other the line ofdraft is varied by reason of the upand-down movement of the front end ofthe thrust-bar, and that such change in the line of draft affects thedepth of cut of the disks at opposite ends of the gangs in a way and toan extent which would not be accomplished by a mere change in the angleof the gangs to t-he tongue from the fact that as the gangs are beingshifted from the position shown in Fig. -t to that in Fig. the frontends of the draw-bars are elevated relatively to the gang-axles. Suchelevation of the drawbars tends to lessen the 4 depth to which theinnermost disks will eut as compared with the disks at the outer endsot' the gangs. By preference I make each draw-bar of a sepa* rate bar ofmetal and unite their t'ront ends to the thrust-bar and to a part orlink, L, by a pivot, 7;.

The forward end of the part L is ratcheted, as at L, its extreme endbeing formed into a hook, l, which takes hold of aircye, loop, orstaple, (l, on the under side of the tongue. This loop or eye is of suchsize and shape that the ratcheted part is free to slide through itwithin certain limits, the hook I supporting the draw-bar againstbackward pull.

is a locking-link pivoted at its lower end upon the pivot and notched atits upper end to engage with a catch or lock-plate, a', pro ]'ectingfrom the seat-standard or other suitable support. The upper end of thislink is formed into a handle within convenient reach ot' the driver, andit will be readily understood that by pulling upward on thislocking-link the driver can move the inner ends of the disk-gangsforward relatively to their outer ends, and vice versa.

\\'hen it is desired to move the inner ends of the gangs backwardrelative to their outer ends, it can be done by releasing thelockinglink from its catch or lock-plate a, when the draft of the teamwill pull the outer ends of the gangs forward relatively to their innerends; or the same end can be attained by pushing downward `upon thelocking-link. lVhen the inner ends of the gangs are pulled forward theupper forward end of the part L of the draw-bar will be thrust throughthe hook and be caught and held by a pawl, M, which is pivotcd at 'm tothe tongue.

N is a tripping-lever pivoted at n to some convenientpart of the mainframe or to the seat-standards a and conuected-by link n to the pawl Mfor the purpose of unlocking the pawl from the ratchet when it isdesired to have the inner ends ot' the gangs moved backward.

By an examination of Figs. i and 5 it will be readily seen that the partL of the drawbar when engaged with either the pawl M or the loop orstaple a will support the 'forward end of the thrust-bar K againstdownward movement, irrespective of the locking-link Z',- or the link lwill perform the same function even though the part L of the drawbar beomitted. Hence, although I prefer to use both of these devices, L andZ', yet I do not wish IOO IIO

to be limited thereby. By an examination of the same figures it will beseen that the inner ends of the gangs can be adjusted to variouspositions and moved forward when in operation by means of the jointeddraw-bar and the link Z', even though the thrust-bar K be omitted; henceI do not wish to be limited to the use of the thrust-bar independentlyof the jointed draw-bar or the locking-link.

P P are scrapers curved to fit with sufficient accuracy the .concavefaces of the disks. Each scraper has a hole in its upper end to receivea rod, upon which they are spaced by means of thinrbles Q Q. The outerend of each series of scrapers is supported by an eyebolt whichsurrounds one of the thimbles, the shank of the bolt passing through oneor a pair of the hangers l', as at b3, Fig. S. Near the rear en d eachscraper-bar is thrust th rough a hole in one of the links j. Thethimbles Q Q are shorter than the thimbles Q.

l Q are coiled springs surrounding the scraper-bar between the thimblesQ Q and the links j', whereby there is a slight longitudinal movement ofthe scraper-bar and its attached scrapers, whenever required. Thus itwill be seen that the thimbles not only serve to connect the scraperswith the scraper-bar, but to space the scrapers, and that while thesprings q q permit the adjacent thimbles to move cndwise relatively tothe links j', yet the scrapers, the thimbles, and

' the scraper-bars move endwise substantially together withoutdisturbing' their working' relation to each other and to the disks, therelative positions of the parts being such that the scrapers areautomatically maintained in about the same position as regards the disksunless moved in one direction or another by reason of some irregularityin the disks themselves or of material which adheresto the y...disks p pare nuts on the end of the scraper-rods. These nuts are so clamped tothe scraper rods or bars, the scrapers, and the spacing-thimbles to eachother and to the springs q q, that the scraper-bars and Scrapers movetogether longitudinally of the gangs whenever required.

As shown in Fig. 7, which is a cross-section of one of the scrapers,they (the Lscrapers) are so formed as to present a rather sharpcutting-edge to the disk to meet the advancing earth when it adheres tothe disk, the upper ends of the scrapers being supported against forwardthrust by the rods O, while their lower ends rest against the thimbles,except in the case of the outer scraper, P', of each gang, which mayhave attached to its lower end a collar, p', which is mounted looselybetween the nut of the gang-axle and the outer disk. I propose to makethese Scrapers of thin steel or other elastic material, which, with theendwise movement of the scraperbar, which is made possible by thesprings q q, will insure a satisfactory operation.

R is a seed-box.

- R R are brackets mounted on the harrowframe and carrying the seed-box.

S S are thin metal strips or plates pro- Vi ded each with three rows ofsimilarly-spaced square or round holes, s s, which register withcorresponding holes in the bottom of the seedbox, as is customary insimilar machines. These strips are arranged in a groove in the bottom ofthe seed-box, the upper one being stationary, the lower one beingadjustable endwise by means of a cam-lever, T, pivoted to the rear wallof the box and engaging with an arm, connected with the lower plate andYprojecting through a slot in the boX.

'1" is a notched segment with which the lever T engages.

It is well known that when distributing guano or other fertilizersdifficulty arises by reason ot' the material arching over above the.delivery-openings, and to obviate such objection I employ arocking-shaft, U, mounted at its ends in the ends of the feed-box andcarrying a series of downward-projecting agitators, u. I propose to usetwo parallel lines or strands of chains or some equivalent form' ofdistributer to assist in the discharge of seed or fertilizer, or both,through the openings in the bottom of the seed-box; and to impart thedesired motions to the agitator and the distributing-chains I propose toconnect them with one of the gang-axles by devices which I .will nowproceed to describe, referring particularly to Figs. l, 2, 4, S, and 9.y

"l is a crank-plate or arm attached to the outer end of one of thegang-axles, preferably by means of the same nut which clamps the axle,disks, and thimbles together.

2 is a crank-rod connected at its lower end to the crank-plate andsliding freely through a loop on the upper end-of an arm, 3, which isadjustable in a plate or clamp on the seedboX at r.

4 is a link exibly lconnected at its upper end to arm 3.

5 is a link suspended at one end upon the link 4 and provided at itsouter end with an eye surrounding the rod 2.

The link 4 is' adjustable relatively to the link 5 or the arm 3, orboth, so that when the arm 3 is adjusted up and down a correspondingadjustment of link 4 may be made, so that the link may be maintained ina substantially horizontal position. The forward end of link 5 isconnected to a crank-arm or lever, 6, of the rocking-shaft U.

7 is another link attached to the crank-rod at its lower end andpreferably adjustable thereon. The upper end of link 7 is connected tothe outer end of arm 8 of a crank-axle, 9 l0 l1, of which the parts 9 llare nearly perpendicular, and are connected at their lower ends by ahorizontal part, l0, the entire crank-axle lever being pivoted uponspurs or their equivalents r fr', projecting from the seed-box.

4l2 is a rod pivoted to the part 10 and sliding through an eye or loop,13, depending IOO IIO

IZO

from the seed-box, and havin g an upturned outer end, 14. i

15 is a line of chain connected to the upturned end 14, passing thencethrough the seed-box just above the metal plate S and out at theopposite end of the box, where it is connected to the lower end ot' alever, Iii, which is pivoted at its upper end, 17, to the seed box orlug projecting theret'ron'l.

18 is a lever pivoted at 1! to the leve: l() and fulcrumed at :2O to alug or post projecting t'rom the seed-box.

21 is a second chain connected to the lower end oli' lever 1S andpassing thence parallel to chain 15 through the seed-box and out to andconnected with the lower end ot a lever, 22, which is t'ulcrumed at 23.

24 is a coiled spring, preferably arranged within the seed-box andconnected to the upper end ot lever :225. 'lhus this spring operates,through lever 22, to move the chain 21 toward that end ot' the box towhich the lever is pivoted, the other chain, 15, being moved in the samedirection by the upturned outer end, 14, of the rod 12 alternately, thcconnections betweenwthe opposite ends ot these chains being of suchcharacter that the spring operates to move the chains inoppositedirections into the position from which they have been moved bythe positive action ot' the other and alternately-acti n devices.

From an examination ot' the drawings it will be readily seen that as thegangs rotate and the crank-rod moves up and down,both chains will bemoved alternately endwise relatively to the seed-box and in such closeproximity to the holes s s as to effect a thorough i distribution ot theseed or the fertilizer, as the case may be.

I am aware that chains have been used as distributers inseeding-machines; but the employment ot' two parallel lines ot' chainarranged in close proximity to each other and to the discharge-openingsin the hopper is uset'ul, particularly in the distrilnition ofi'tertilizers, because their alteri'iating movements ettectually preventchoking or cloggin ot the material, and thus facilitate its delivery.

It will be readily understood that by adjusting the height ot the armthe distance traveled by the chains at each revolution ot the gang-axlesmaybe varied, and that by reason ofthe crank-rod vibrating about the arm3 its operation is that of a lever with an adjustable fulcrum. It willfurther be seen that the character of the rock-shaft and chain-operatingdevices is such that the movements ot' these parts is not materiallyat'tected by any variation otl the positions ot' the `gangs relativetothe feed-box which will occur under the ordinary operations for whichthe machine will be employed. Ot' course such variations are much lessthan would occur if the gangs were mounted, as they frequently are inmachines of this ch aracter-to wit, with the hangs ers near the innerends of the gangs and the adj listing-rods, links, or draw-bars attachedto the outer ends of the axles.

To provide again st undue cramping or wear of the crank-rod where it isconnected with the crank-plate, I prefer to use the construction shownenlarged in lfig. S, in which the crank-plate is provided with anottset, so that the part 25 stands out at some distance from the laceot' the disk, and is provided with a 'hole to receive the bent lowerend, 26, of the crank-rod. The edges ol the hole are beveled or rounded,so as to tit closely and prevent lost motion while permitting thevibrations ot' the gangs without cramping.

27 B7 are washers, one on either side of the pla-te, and 2S is a pin orsplit key passing through the end 2U to preventaccidental displacementot these parts.

In `Fig. 9 I have shown enlarged a convenient form otl oil-cu p, whichmay be applied to either ot' the bearings C or E, and in which C2 is thecup adapted to receive the oil, and, when preferred, cotton-waste. c isthe cap. c is a pin projecting upward trom "the cup; c2, a coiledspring; c3, a washer which is pressed down upon the coiled spring andheld by riveting the upper end of the pin or by a nut. The cap can belifted slightly and then swung around on the pin as a pivot, the oilpoured in, and the cap swung back with its sunken portion. inside thecup, in which position the spring will hold it.
